All of the carbon fiber fins from Futures are gunna be around 90$... They do have some composite fins with the v2 foil in them (like the 3 2 1s) that are less expensive... Any of the futures fins with a V2 foil are sweet IMO... If you guys are looking for some extra speed (lift) the Futures Solus fins are very fast... The offer almost as much lift as the Scimitar fins but they are a bit looser for spinning and such. I prefer the BlackStixx AM1 over the F4... little less hold. If you are looking for even more hold from your fins the Machados work well in a twinzer setup also. After riding all of them, the Solus are my favorite so far... fast but still moderately loose.

I felt like the TWP boards were sliding a bit when pumping... I never got a chance to try the Machado fins in one of those boards but I think the extra surface area would help.

Piper,
did you try my Machados? RJ had them in the Z3 at the PB..I found them a little slower and looser then the black stix. I come from ocean surfing so I like hold...a lot of hold and the black stick store speed in the bottom turns rather then slowing like the 321s.

Fins are like tires on a race car or a dirt bike. What works for me may not work for you. As you all can see Piper likes what he has because he has tested and played with different fins and I can't express how much fun it is.
